I lived in this building from 6/08 to 6/11 and had 4 separate infestions. The first bedbug extermination was done in 11/09, another in 7/10, another in 12/10 and another in 6/11.The last 2 infestations were worse because they spread into multiple rooms and also required 3+ treatments. The super refused to seal openings in baseboards etc. as the exterminator recommended and also the bldg. has no bldg.-wide mgt. plan , like chking adjacent apt.s. So there's no reason to believe that the problem
